ω the velocity of a body rotating about a specified axis measured as the rate of change of the angle subtended at that axis by the path of the body |
angular velocity
The rate of change of an angle associated with an object with respect to some reference point. For example, the average angular velocity of an object moving around a central reference point once every second is 2π radians per second; the Earth spins around its axis with an angular velocity of 2π radians per day. Also called angular frequency. |
